[origin: US2012321080A1] A digital television receiver device supporting two or more different conditional access systems has a content receiver that obtains an encrypted content stream and a processor. A content stream decrypter decrypts an encrypted content stream for conditional access or copy protection from at least one of the following interfaces: an interface to a CableCARD, an interface to a Common Interface Module consumer replaceable module for use with conditional access key management and content stream conditional access decryption and content stream copy protection re-encryption, and at least one of the following interfaces: an interface to a USB2 compatible consumer replaceable module, an interface to an enhanced SIM consumer replaceable card. Other variations are disclosed. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
